A simple all-in-one TBA820M from the past that many of you know and experience. Despite its small size, it accomplishes great work from its height according to its time, its price is cheap, the area it covers is small and its working tension is quite flexible. I have tried to make the two circuit boards…
The modified C-Class Sixteen model of the Harman card company in 1976 is able to deliver 400 watts of power through a 4-ohm speaker with an AB class Amplifier circuit . The power transistors 2SC5200 and 2SA1943 use the TL072 opamp in the 400w anfi circuit. The OPA2134 opamp is said to be of better…
For a long time I was going to share with you the materials on assembling a transistor amplifier with unipolar power, assembled in retro-topology, which is still of interest to some radio amateurs. At the forum Diyaudio this ULF can be found under the name APEXAX6. This circuit does not need DC Protect, because the…

It also deals with it by means of…
Mono power module, based on LM3886 application. He enjoys very high popularity and good reputation even among audiophiles who are “overly sensitive to everything that is integrated”. The LM3886 integrated circuit is based on bipolar transistors. It is equipped with protection circuitry for overheating, overload, and a very useful muting circuit for switching on and…
TPA3116 Class D Amplifier Circuit A small class-D mid-range stereo headset that will be used in car headphones, active speakers, or PC-audio. The amplifier module is based on the TPA3116 circuit comprising two bridged power amplifier channels with common switching, muting and protection circuits. TPA3116 Circuit schematic The TPA3116 power amplifier schematic diagram. The U1…
The lamp used in the project is PCL805 tube. Older Readers may remember it because it was used in the vertical deflection pattern of most tube TVs. Today it can be obtained for free or almost free because it has not found use in today’s acoustic amplifiers built by many enthusiasts. What parameters does this…
LM4952 It is not always necessary to have a high power audio amplifier. It is enough to power the small speakers with much less power. The presented amplifier meets this condition. It has a power of 2 × 3 W / 4 V, and additionally allows electronic volume control. LM4952 The module is based on…
Guitar Amplifier circuit the signal is directed to the tip of the TDA2050. The output power is 25 W with a load of 4 ? (17 W at 8 ?). This block is equipped with an additional “CD / MP3 Player” input and three “Slave Out” outputs (for other terminals or recording equipment), “Headphones” (for…
The amplifier module is based on the TPA2005 chip with a bridged TPA2005 power amplifier capable of delivering up to 8V of almost 1.4W at 5V. Thanks to the small operating voltage (2.5V), it was possible to power the typical Lipo 14500 without additional boosters . The audio signal from the IN jack is fed…
